If Smoot Hawley was the cause of the Great Depression (odd considering it was passed AFTER the stock market crashed) then how do we explain the fact that US GDP increased by 60% during the 4 years of the highest tariff in US History – the so called “Tariff Of Abominations”? Surely that should have caused an even worse depression instead of growing the American economy, if tariffs cause depressions, but that’s not what happened. Why?
